Repotting large Blc. Hausermann's holiday into S/H

[shahrezsyed]

I purchased a large Blc. Hausermann's holiday in an 8.5" pot around two months ago and since then, I have noticed lots of root growth as well as the emergence of 4 new growths/pseudobulbs emerging from four distinct corners of the plant. I really want to repot the plant into a large pot and let it grow undisturbed for a long time as I feel like this Blc. has the potential to turn into quite a display specimen over time.
I'm planning to repot it into a huge food safe container with Leca. Is there any reason I shouldn't repot into a container this large or am I good to go? I'm fairly new to semi-hydroponics so I didn't want to take any chances before taking the plunge with this particular orchid.
Sorry for the rotated pictures, they rotated like this automatically upon uploading...
